I've finally gotten around to starting Mafia 3 -- in an attempt to get some escape from the real world.
It's much harder to get into, and not nearly as satisfying, but it does grow on you.. The acting is great, the story is good (though it can't compare to Mafia 2), and it's BIG.
I definitely enjoyed 2 more.. Mafia 3 seems to be more on the bandwagon of making you grind away doing millions of little missions hunting every square inch of map, slowly unlocking perks and collecting a million tiny little items hidden behind millions of locked doors, etc. And a huge set of little micro-management of upgrade tree, etc. Where 2 was more focused on a linear story and less grinding. But still, the developers of these games have a real vision for creating a world and story that feels gritty and real.
The music is, as with the Mafia 1 and 2, absolutely outstanding, and adds a huge amount to the game.
It's amazing how these games make you feel like you are living in these worlds..
